Finding Leads to Increase in Risk Level
Concord, NH - The New Hampshire Department of Health and Human Services
(DHHS) is today announcing a positive test result for Eastern Equine
Encephalitis (EEE) in a mule in the town of Candia. This finding raises
the risk level for human illness in Candia from “Moderate” to “High.” The
surrounding towns of Auburn, Chester, Hooksett, and Raymond will be
increased from “Low” to “Moderate” risk.
“This is the first animal in New Hampshire to test positive for EEE this
season,” said DHHS Public Health Director Dr. José Montero. “This is
another indicator that there are EEE virus and West Nile Virus infected
mosquitoes in the State. The end of August through mid-October is the time
that people are at the greatest risk for contracting a mosquito-borne
disease. It is so important for everyone in the State, no matter where you
live, to take simple precautions to prevent being bitten by mosquitoes.”
So far this season New Hampshire’s Public Health Lab has tested 2,908
batches of mosquitoes. Of those, 6 tested positive for EEE and none have
tested positive for West Nile Virus (WNV). Additionally, one person was
diagnosed with EEE virus infection in August.
EEE is a serious disease that carries a high mortality rate for those who
contract the serious encephalitis form of the illness. Symptoms may
include high fever, severe headache, and stiff neck. There is no treatment
for the disease, which can lead to seizures and coma. Symptoms usually
occur 4 to 10 days after being bitten. Symptoms of WNV disease often
appear 4 to 10 days after being bitten. If you or someone you know is
experiencing flu-like symptoms, including fever and headache, contact your
local medical provider.
Protect yourself and your family from WNV and EEE with these simple steps:
· Use an effective mosquito repellant when you’re outside
· Wear long sleeves and pants at dawn and dusk when mosquitoes are most
· Remove standing water from around your home so mosquitoes do not have
a place to breed
· Check doors and windows to ensure screens are in place and in good
condition to prevent mosquitoes from entering your home

Prevention Guidelines for West Nile Virus and
Eastern Equine Encephalitis
NH Department of Health and Human Services, Division of Public Health
1. Eliminate standing water and other mosquito breeding locations.
In warm weather, mosquitoes can breed in any puddle that lasts more than 4
· Remove old tires from your property.
· Dispose of tin cans, plastic containers, ceramic pots, or other
containers. Don’t overlook containers that have become overgrown
by aquatic vegetation.
· Drill holes in the bottom of recycling containers that are left
· Make sure roof gutters are clean and draining properly.
· Clean and chlorinate swimming pools and hot tubs. If not in use,
keep empty and covered and keep covers free of standing water.
· Aerate garden ponds or stock them with fish.
· Turn over wheelbarrows and change water in birdbaths at least
· Turn over plastic wading pools when not in use.
· Remind or help neighbors to eliminate breeding sites on their
2. Be aware of where mosquitoes live and breed and keep them from entering
· Mosquitoes lay their eggs in standing water. Weeds, tall grass, and
bushes provide an outdoor home for adult mosquitoes, including
several species commonly associated with West Nile virus and eastern
· Mosquitoes can enter homes through unscreened windows or doors, or
broken screens. Make sure that doors and windows have tight-fitting
screens. Repair or replace all screens in your home that have tears
· Resting mosquitoes can often be flushed from indoor resting sites by
using sweeping motions under beds, behind bedside tables etc. and
once in flight, exterminated prior to sleeping at night.
3. Protect yourself from mosquito bites.
· If outside during evening, nighttime, and dawn hours when mosquitoes
are most active and likely to bite, children and adults should wear
protective clothing such as long pants, long-sleeved shirts, and
· Consider the use of an effective insect repellent, such as one
containing DEET. A repellent containing 30% or less DEET
(N,N-diethyl-methyl-meta-toluamide) for children and adults. Use DEET
according to the manufacturer's directions. Children should not apply
DEET to themselves. Repellents that contain Picaridin,
para-menthane-diol or oil of lemon eucalyptus have also been
determined to be effective.
· Vitamin B, ultrasonic devices, incense, and bug zappers have not been
shown to be effective in preventing mosquito bites.
